54 Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetworx for DeviceNet
Configure Peer
Communication
This section will describe how to configure the POINT I/O and ArmorPoint
I/O DeviceLogix module to consume data from peers. The POINT I/O
DeviceLogix module can use data from other modules to affect the
DeviceLogix program.
The module can perform the following functions:
•
Get Change-Of-State (COS) data from up to eight I/O modules or
peers.
•
Each peer can have up to 24 bytes of data.
•
Each peer has its own expected packet rate.
•
Each peer has its own status bit that can be used in logic.
•
The data from each peer can be digital (bit), analog (16-bit words), or a
mixture of both.
The following functions are not supported:
•
Make a connection.
•
Configure a peer.
•
Control outputs on a peer.
•
Listen to a peer that is on another network.
The module can only listen to peers on the backplane or local
DeviceNet network.
Zone Control
This is a legacy parameter for DeviceLogix and ZIP. It shows the state
of Zone Control, whether it is enabled or disabled.
Sequential Auto
Address
This parameter should only be used in a DeviceNet system. It is used
to set another POINT I/O or ArmorPOINT I/O module to the right of
this module to a node address one greater than this module.
This message will propagate to all modules to the right. Each address
will change to one greater than its neighbor.
Broadcast Baud
Rate
This parameter should only be used in a DeviceNet system. It is used
to set another POINT I/O or ArmorPoint I/O module to the right of this
module to the desired baud rate.
1: 125 kHz
2: 250 kHz
3: 500 kHz
The only way a module can achieve a 1 MHz baud rate is by using the
AutoBaud feature.
Broadcast
AutoBaud
This parameter should only be used in a DeviceNet system. It is used
to set another POINT I/O or ArmorPoint I/O module to the right of this
module to Autobaud (enable) or used to save the baud rate (disable).
